Calling for a specific branch does not seem to work

tested with a pipeline in the ops repo that had not been created in `main`, yet
- create branch in ops repo
- create a new pipeline in ops repo
- try to trigger pipeline as follows:
```
deploy:
# only deploy if not pull request
runs-on: ubuntu-latest
steps:
- name: Deploy Stage
uses: bitovi/github-actions-bitops-ci-cd@0.5.0
with:
github-token: ${{ secrets.OPERATIONS_REPO_TOKEN }}
org: bitovi
repo: operations-repo
branch: some-branch
workflow: new-workflow.yaml
```

Start by reproducing the pipeline described in the issue: create a branch and a new pipeline in the ops repository, then use the shown GitHub Actions step with branch `some-branch` and workflow `new-workflow.yaml`. Compare the result with triggering the same workflow from `main`; done means the specified branch reliably triggers the requested workflow.
